get some benzocaine (oral numbing gel/liquid) and some ibuprofen, apply the benzo frequently and take 400mg of ibuprofen in the morning, 400 at lunch and 400 at dinner. you won't feel a thing. not safe to take that much constantly, but for a week you'll be fine.

but watch for infection because that will fuck you up. i doubt a small chip is going to turn infected that quick tho.
